Subject: test/util: expect_msg_seq()

job_spec.lua on AppVeyor (Windows) often fails like this:

      FAILED  ] C:/projects/neovim/test/functional\core\job_spec.lua @ 72: jobs changes to given `cwd` directory
    C:/projects/neovim/test/functional\core\job_spec.lua:81: Expected objects to be the same.
    Passed in:
    (table) {
      [1] = 'notification'
      [2] = 'stdout'
     *[3] = {
        [1] = 0
       *[2] = {
          [1] = 'C:\projects\neovim\Xtest-tmpdir\nvimmSjq1S\0' } } }
    Expected:
    (table) {
      [1] = 'notification'
      [2] = 'stdout'
     *[3] = {
        [1] = 0
       *[2] = {
          [1] = 'C:\projects\neovim\Xtest-tmpdir\nvimmSjq1S\0'
         *[2] = '' } } }
    stack traceback:

Message chunking is non-deterministic, so we need to try different
variants.
